ItemIsMovable???

[konvex]

Hi,
I want to move an item, but only if I press the right mousebutton.
Can somebody tell me how to do this?
I've tried this:

void GraphicsScene::mousePressEvent(QGraphicsSceneMouseEvent *e)
{
pos=e->scenePos();
end=e->scenePos();
item = new EllipseItem(pos.x(), pos.y(),10,10);
item2 = new EllipseItem(end.x(), end.y(),10,10);
 
if(e->button() == Qt::LeftButton)
{
   if(itemAt(pos))
   { QGraphicsScene::mousePressEvent(e); }
 
   else
   {
   addItem(item);
   addItem(item2);
 
   linie = new LineItem(item,item2);
   addItem(linie);
   }
}
 
if(e->button() == Qt::RightButton)
{
   item->setFlags(QGraphicsItem::ItemIsMovable);
   item2->setFlags(QGraphicsItem::ItemIsMovable);
}
        //this doesn't works
}

void GraphicsScene::mousePressEvent(QGraphicsSceneMouseEvent *e)
{
pos=e->scenePos();
end=e->scenePos();
item = new EllipseItem(pos.x(), pos.y(),10,10);
item2 = new EllipseItem(end.x(), end.y(),10,10);
 
if(e->button() == Qt::LeftButton)
{
   if(itemAt(pos))
   { QGraphicsScene::mousePressEvent(e); }
   
   else
   {
   addItem(item);
   addItem(item2);

   linie = new LineItem(item,item2);
   addItem(linie);
   }
}

if(e->button() == Qt::RightButton)
{
   item->setFlags(QGraphicsItem::ItemIsMovable);
   item2->setFlags(QGraphicsItem::ItemIsMovable);
}
        //this doesn't works
}

See QGraphicsItem::setAcceptedMouseButtons().

The right button works. But although the items are not movable?!

When you press the right mouse button, two items are created but these aren't added to scene. So the scene does not contain anything to mark with ItemIsMovable flag...
